TomTom satnav / Linux box and screen (Reepham NR10)

This is an ancient TomTom Go 300 satnav, complete with padded bag. It works fine but the maps will be old and the screen resolution is poor, so you might not want to use it for its intended purpose.

However, it's also a Linux device with a touchscreen and a decent-size speaker, and I believe it's hackable. You might be able to turn it into a little display unit for home automation or whatnot.
